Can you try to charge the battery while the computer is off (eg. for 2hrs) then observe.

If the battery charge is still 0% after doing the above procedure then it's likely that the battery is showing signs of failure. In this case, I recommend you check if the battery still has a warranty and check with the reseller for a replacement battery.

You mentioned that you purchased a new battery for the G450 system. To replace this battery, you will need to contact the person or the store that sold you this battery (eg. If you purchased it from Amazon.com, you will need to contact Amazon) as the battery can only be replaced from the place of purchase.
